Understanding the Highway 101 Closures

Highway 101 drivers heading through San Francisco face significant weekend lane reductions as vital rehabilitation work continues along a heavily congested stretch. The construction specifically targets the busy Hospital Curve area situated between Cesar Chavez and 17th streets.

Construction Schedule and Detour Info

Caltrans officials scheduled the shutdown to begin promptly at 11 p.m. on Friday, giving work crews maximum time to repave the southbound lanes. The roadway is slated to fully reopen to regular traffic by 6 a.m. on Monday morning.

Drivers navigating through the region should keep several key operational details in mind:

All southbound lanes and one northbound lane are completely shut down during the active construction window.
Caltrans strongly recommends that southbound travelers utilize Interstate 280 as their primary alternate route.
This weekend undertaking marks the third total shutdown required for this specific repaving initiative.

The overarching infrastructure rehabilitation project originally commenced back in the fall of 2025 to upgrade aging pavement. Local motorists should prepare for significant delays when navigating the affected corridor throughout the active construction hours.

Looking ahead, a fourth and final closure for this broader series of essential repairs is already scheduled for November 6. Planning ahead and utilizing recommended travel tools will help all regional drivers avoid unnecessary gridlock.
